ST. LOUIS – Drivers in north St. Louis county who use I-270 regularly should be aware of an upcoming change which may impact how they get to the interstate.
First, crews will close the westbound lane of Pershall Road between New Florissant and Hanley Road at 7 a.m. on Monday, May 9.
For six months, this section of Pershall Road will have only one eastbound lane. After construction is completed, this portion of Pershall Road will reopen as an eastbound only, two lane outer road.
